title: Can the retroperitoneal approach be used for ruptured abdominal aortic aneurysms?
abstract: The retroperitoneal approach for elective treatment of abdominal aortic aneurysms is an accepted alternative to midline transperitoneal approaches and may provide less physiologic insult and a smoother postoperative course. In recent years we have preferentially used the extended retroperitoneal approach for ruptured abdominal aortic aneurysms to derive similar physiologic benefits for these patients. Over a 6-year period (1983 to 1989) 76 cases of ruptured abdominal aortic aneurysms were treated by emergency aortic replacement. After exclusion of 13 patients whose aneurysmal ruptures were unusual, such as aortoenteric fistula, aortocaval fistula, chronic contained rupture, or visceral involvement, 63 patients were retrospectively studied. Thirty-eight patients were treated via a standard transperitoneal celiotomy and 25 via a left retroperitoneal incision. No significant differences were found between the two groups in regard to cardiac or pulmonary function or duration of preoperative hypotension. Operative mortality was lower in the retroperitoneal group (three of 25, 12%) as compared to the transperitoneal group (13 of 38, 34.2%). Furthermore, the retroperitoneal group required less ventilatory support and tolerated enteral feedings quickly. Length of stay in the hospital was also significantly reduced in the retroperitoneal group. These data indicate that many ruptured abdominal aortic aneurysms can be successfully treated through the left retroperitoneal approach. In this nonrandomized clinical series increased survival rates and shorter periods of postoperative recovery were noted in the patients operated with the retroperitoneal approach.
